6PPD and IPPD

6PPD (N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine) and IPPD (N-isopropyl-N′-phenyl-p-phenylenediamine) are highly effective antioxidants used in the rubber industry. They serve as protective additives that significantly enhance the durability and resistance of rubber products against environmental factors such as ozone, oxygen, and heat.
